's general knowledge of relation of pulmonary tuberculosis and lung cancer
Is pulmonary tuberculosis developed into lung cancer: Clinical the intersection of scientific research and materials up until now brief on, pulmonary tuberculosis and emergence of lung cancer have direct relation.
Pulmonary tuberculosis whether the intersection of tuberculosis and fungus infect the intersection of respiratory tract and infectious disease that cause, and lung cancer to smoke, air pollution and low relevant tumour diseases of immunological function. But pulmonary tuberculosis causes the chronic damage to the lung, has influenced the bronchus to affix leather normal function and antiviral state of immunity of organism, there is indirect facilitation on emergence of lung cancer, the intersection of pulmonary tuberculosis and focus of calcification, tuberculosis cicatrix, getting outmoded the intersection of cavity and wall and their bronchus, leather the intersection of cell and hyperplasia, hyperplasia,etc. relate with the emergence of lung cancer at the alveolus. Carcinogenic incubation period when people suffered from lung cancer is very long, it generally takes 10- 30 years, suffer from pulmonary tuberculosis when being young, lung cancer appeared in the cooking stove of the calcification after curing, some patients suffered from lung cancer again after old age, often find outmoded pulmonary tuberculosis amalgamates the case of lung cancer on clinic.
If lung cancer coexists with active tuberculosis. Easier to cause a difficult diagnosing. Tuberculosis patients have many the generally young ones, lung cancer patients have many old age person, but the tuberculosis old age trend has already shown at home at present, the proportion of the young patient of lung cancer is increasing too, when both existing, often because of finding the tubercle bacillus and diagnosis of ignoring lung cancer in the tuberculosis focal existence or phlegm. To the pulmonary tuberculosis patient, meet the following situations, the ones that should highly watch out for lung cancer and coexist are possible:
The male patient over 1.40, smoke in the history for a long time;
2.Have irritation to cough, the continuation chest aches, breathe hard, become thin, the persons who do not correspond to X-ray pathological change of symptom and the going on is aggravated;
3.Amalgamate water of chest, water of chest increases fast, even the shadow is expanded, or present the new focus on other positions;
5. see X-ray chest slice whether because lump is show in round and group is blocky, last 24cm diameter, lump be divided foliate to be taken the form of, edge abnormality is presented the burr kind, not with enlargement of lymph nodes and lung of lung door one.
